software

just uploading them to photobucket and i hope they will still look ok (they are a bit bright as i didnt set up the scanner properly but i think you can see enough =/the 2x12v is pretty much final i just might change a thing or two look vise once i got ALL the measurements finalised

the 2x12h is still up to debate though. after the discussion in the past thread i made the neccessary redesign and i think it should roll off good
=)might change a couple of measurements, but the whole box i think will stay the same

what do you think folks?

That vertical cab needs to be shorter. With b=2a, you're setting yourself up for resonance problems. 20quot;w x 32quot;h x 12quot;d would be better. Do a web search on the quot;golden ratioquot; as it applies to speaker design. Not only does it reduce resonance, but rectangles designed using the ratio are more pleasing to the eye - weird but true, it goes back Greek architecture. the mathematical theory behind it is based on the Fibonacci (sp?) sequence, but now we're getting in WAY too deep.

Of course, the venerable Marshall 4x12 breaks this quot;rulequot; into little pieces. I once got a bit out of control on the AX84.com forum, and applied the Fibonacci sequence to show that you can't use just one Marshall stack; they simply don't look right until you have four.

With the Fibonacci sequence, does it matter if the 2 speakers are side by side, or staggered on an angle like in the above diagram.
